能够通过外部刺激而多向变形的功能分子晶体具有在诸如机械传感器和柔性器件的各种应用中使用的潜力。我们报道了两种2，2 ′：6′，2 ′′-三联吡啶衍生物的有机晶体，它们分别被荧光萘基（1）和蒽基（2）取代，在机械应力作用下表现出多面柔性弯曲和弹性，其性质通过纳米压痕、单晶X射线结构分析和能量框架计算进行了详细的评估。
Functional molecular crystals capable of multidirectional deformation by external stimuli have the potential to be used in various applications such as mechanosensors and flexible devices. We report two organic crystals of 2,2′:6′,2′′-terpyridine derivatives each substituted with luminescent naphthyl (1) and anthryl (2) moieties, displaying multi-faceted flexible bending with elasticity in response to mechanical stress, whose properties are evaluated in detail using their nanoindentations, single crystal X-ray structure analyses, and energy frame calculations.
